Melles Griot 633-nm lasers have been field proven in applications ranging from simple alignment and pointing at construction sites and sawmills to precision measurement and ranging in the rigors of space. Typical lifetime is as high as 50,000 operating hours. 

  • High-power lasers, with output up to 35 mW, available in cylindrical or rectangular configurations, are ideal for Raman spectroscopy, fast scanning, and test-and-measurement applications that benefit from increased signal-to-noise performance.
  • Stabilized single-frequency lasers, with coherence lengths measured in kilometers, are ideal for calibration, precision measurement, and ranging applications.
  • Class II lasers (IEC Class 2), with power less than 0.95 mW, are ideal for pointing, alignment, and teaching applications where eye safety is of paramount concern.
  • Self-contained lasers are ideal for general-purpose alignment applications.

Systems are offered in both self-contained and cylindrical configurations with separate power supply.

Cylindrical HeNe Lasers :

Melles Griot manufactures a wide variety of cylindrical HeNe laser systems, only a few of which are represented here. All laser heads are mounted in rugged aluminum housings and come with a matched power supply. All systems meet CDRH requirements for laser equipment, and all 230-Vac versions are CE compliant. Lasers are available in randomly polarized (LHR series) or linearly polarized (LHP series) versions. If you have a special requirement that cannot be satisfied by one of these lasers, please contact us.

Self-Contained HeNe Lasers :

Self-contained HeNe lasers combine the laser tube and power supply in a single, compact package. They are ideal for alignment, component testing, and general laboratory use, as well as for educational and high-volume OEM applications. Melles Griot offers two package configurations: a stand-alone rectangular package that can sit directly on a laboratory table, and a cylindrical package that can be mounted in a conventional laser holder or attached to a table using the included snap-in base.

Green Helium Neon Lasers (543nm)

Green HeNe lasers have up to five times the visibility of red lasers with the same output power. Consequently, they are ideal for aiming and pointing applications. They also are the lasers of choice for many biotechnology, cytometry, microscopy, and graphics applications, since the wavelength closely corresponds to the peak absorption bands of fluorescent dyes, reagents, and film.

Green HeNe lasers are available with powers ranging from 0.20 mW to 2.00 mW, in linearly and randomly polarized configurations.

Melles Griot stabilized helium neon laser systems are ideal for applications such as metrology, interferometry, and surface defect inspection that require a single, invariant frequency. These single-longitudinal-mode systems have a coherence length measured in kilometers, and exhibit excellent power stability for long periods of time. They permit highly repeatable, highly accurate measurements with superb resolution. The output is an economical and reliable calibration reference and a well-defined low-noise frequency source for fiber-optic and diode laser testing. Both output power and frequency can be varied over a wide range; however, changing the power will also change the frequency and vice versa. Critical specifications include:

  • 1-MHz frequency stability at 473.61254 THz
  • <0.2% power fluctuation over eight hours
  • Frequency tunable over 300 MHz
  • Linear polarization with >5000:1 extinction ratio.
